Android 是否将动态按钮布局设置为没有id的XML文件?
所以我只为按钮创建了XML布局 buttons.xmlAndroid 是否将动态按钮布局设置为没有id的XML文件?,android,Android,所以我只为按钮创建了XML布局 buttons.xml <?xml version="1.0" encoding="utf-8"?> <Button xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="35dp" android:layout_height="35dp" android:layout_marginLeft="5dp" an
<?xml version="1.0" encoding="utf-8"?>
<Button xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="35dp"
android:layout_height="35dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:background="@drawable/b1" >
</Button>
那么,如何在不使用id的情况下将buttons.xml布局设置为btn呢 您可以这样做:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:utilidades="http://schemas.android.com/apk/res/com.movidromo.ifilmfest"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/buttonContainer">
</LinearLayout >
您可以通过编程方式设置
高度
宽度
等
布局自定义按钮.xml
<?xml version="1.0" encoding="utf-8"?>
<Button xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:drawablePadding="5dp"
android:background="@android:color/transparent"
android:gravity="center"
android:singleLine="true">
</Button>
我希望这能帮助你。当我使用按钮btn=(按钮)布局时,从(这个)变平。充气(R.layout.buttons,null);所以它在xml文件中包含了数学高度和宽度!
Button yourNewButton = new Button (getBaseContext());
LinearLayout.LayoutParams lparams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
lparams.setMargins(0, 0, 0, 0);
yourNewButton.setLayoutParams(lparams);
yourNewButton.setPadding(0, 0, 0, 0);
yourNewButton.setGravity(Gravity.CENTER);
yourNewButton.setBackgroundResource(R.drawable.yourBackground);
LinearLayout layButtons = (LinearLayout) findViewById(R.id.buttonContainer);
layButtons.addView(yourNewButton);

private void createView() {
btn = (Button)(context.getLayoutInflater().inflate(R.layout.custom_button, null));
btn.setCompoundDrawablesWithIntrinsicBounds(0, iconId, 0, 0);
btn.setText(btnText);
btn.setTextColor(btnTextColor);
btn.setTextSize(btnTextSize);
btn.setBackgroundDrawable(btnBackGrad);
btn.setMinimumHeight(50);
btn.setWidth(50);
btn.setPadding(0, 5, 0, 0);
